Abstract

This invention discloses a highly stable extended texturing machine unit, relating to the field of textile machinery technology. It includes a texturing machine body, with a machine head on one side and a tension adjustment and stabilizing mechanism on the other side. Through the arrangement of a second component within the tension adjustment and stabilizing mechanism, and with the cooperation of a tension adjusting body and its strain gauges, the tension of the transmission chain is fed back, thereby adjusting the tension in a timely manner to ensure it is always in a reasonable pre-tension state. This avoids transmission misalignment caused by slackness, ensuring stable operation of key components within the texturing machine body that are synchronously transmitted with the transmission chain. It prevents fluctuations in the yarn draw ratio caused by inconsistent rotational speeds of the rollers due to slack or excessive tightness of the transmission chain, which could lead to sudden changes in yarn tension and defects such as "stiff yarn" and "loose loops," affecting the fineness uniformity of the finished yarn. By maintaining the stability of the chain transmission, it indirectly ensures constant yarn tension and improves the product qualification rate.

Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, specifically to a highly stable extended texturing machine unit. Background Technology

[0002] In the chemical fiber and textile industry, elastic yarn is a key raw material for producing various clothing fabrics, home textiles, and industrial fabrics. Its production quality and efficiency directly impact a company's market competitiveness. High-stability, extended-length texturing machines, as core equipment for producing elastic yarn, effectively improve the stability and consistency of processes such as yarn heating, deformation, and setting through structural optimization and functional upgrades of traditional texturing machines. This plays a crucial role in meeting market demands for high-quality elastic yarn.

[0003] However, existing high-stability extended texturing machines still have many shortcomings in the chain drive system. Firstly, the lack of an effective tension adjustment component means that during long-term operation, factors such as wear and temperature changes cause a decrease in chain tension, leading to problems like chain slack and skipped teeth. This not only reduces transmission efficiency and increases equipment energy consumption but can also cause fluctuations in yarn tension, resulting in quality defects such as uneven thickness and inconsistent elasticity of the elastic yarn. In severe cases, it can even cause chain breakage, interrupting production and increasing equipment maintenance costs and downtime.

[0004] Secondly, during operation, existing texturing units are prone to chain misalignment due to factors such as equipment vibration, uneven load distribution, and chain installation errors. Once the chain deviates, its meshing position with the sprocket deviates from the normal trajectory, resulting in uneven stress distribution between the chain rollers and sprocket teeth. This causes excessive loads in localized areas, accelerating tooth wear, scratches, and even tooth breakage, further exacerbating chain and sprocket wear, generating abnormal noise, and disrupting the stability of the yarn drive, affecting the processing accuracy and product quality of the elastic yarn. In addition, chain misalignment may cause interference with surrounding components, leading to production line shutdowns for maintenance and affecting delivery cycles. Furthermore, elastic yarn produced before and after the malfunction may experience batch quality problems due to unstable tension, such as uneven dyeing and decreased breaking strength, increasing the scrap rate. Damaged components also pose safety hazards, further limiting the stable operation and production efficiency of the texturing unit.

[0005] Therefore, this invention proposes a highly stable extended type texturing unit to solve the above problems. Summary of the Invention

A magnetorheological fluid chamber is formed in the side of the positioning plate away from the T-slot. A connecting groove is formed on the positioning plate between the magnetorheological fluid chamber and the T-slot, connecting the T-slot and the magnetorheological fluid chamber. A guide groove is fixedly connected inside the magnetorheological fluid chamber. An electromagnetic coil is fixedly connected to the side of the guide groove away from the T-slot. The guide groove is electrically connected to an external power source. An injection port is fixedly connected above the outer surface of the positioning plate away from the T-slot, and an exhaust port is fixedly connected below the outer surface of the positioning plate away from the T-slot.

[0014] Preferably, the auxiliary transmission guide mechanism includes positioning blocks, two of which are fixedly connected to two positioning discs respectively. An L-shaped rod is fixedly connected to the positioning block. An inner cavity is opened at the end of the L-shaped rod away from the positioning block. An air inlet pipe is fixedly connected to the bottom of the inner cavity of the L-shaped rod. A Hall switch is fixedly connected to one side of the inner cavity of the L-shaped rod.

[0018] Preferably, the L-shaped rod is inclined, the air inlet pipe is connected to an external air pump, the guide body is composed of a column rod and a U-shaped block, and the contact is on the same parallel line as the Hall switch.

[0019] Compared with the prior art, the present invention provides a highly stable extended texturing unit, which has the following beneficial effects:

[0020] 1. By setting the first component in the tension adjustment and stabilizing mechanism, under the extension and retraction control of the electric telescopic rod, the pawl restricts the ratchet, preventing the tension adjustment from flipping when the tension adjustment body adjusts the tension of the transmission chain. Under the restriction of the ratchet on the ratchet, the one-way locking characteristic avoids the problem of tension loss of control caused by load fluctuations or unexpected external forces. The meshing characteristics of the ratchet and pawl determine that the tension adjustment and stabilizing mechanism can adjust the tension in one direction. For example, when the tension decreases, the tension is increased to make the transmission chain tighten. With the assistance of the electric telescopic rod, when the tension is too large, the electric telescopic rod can be retracted to release the restriction on the ratchet, causing it to reverse and reduce the tension. After that, the electric telescopic rod extends, restoring the one-way locking of the pawl on the ratchet, thus making the tension adjustment more flexible while allowing for one-way adjustment.

[0021] 2. By setting up the second component within the tension adjustment and stabilization mechanism, and with the cooperation of the tension adjustment body and its strain gauges, the tension of the transmission chain is fed back, thereby adjusting the tension force in a timely manner to ensure that it is always in a reasonable pre-tension state. This avoids transmission misalignment caused by slackness, and thus ensures the stable operation of key components such as the transmission chain and other synchronously transmitted parts within the texturing machine. It also prevents the inconsistent speed of each roller due to slack or excessive tightness of the transmission chain, which could cause fluctuations in the yarn draw ratio, sudden changes in yarn tension, and defects such as "stiff yarn" and "loose loop yarn," affecting the fineness uniformity of the finished yarn. By maintaining the stability of the chain transmission, the constant yarn tension is indirectly guaranteed, thereby improving the product qualification rate.

[0022] 3. The third component within the tension adjustment and stabilization mechanism is set up in conjunction with the magnetorheological fluid in the magnetorheological fluid chamber while adjusting the tension force. Strain gauges on the tension regulator monitor the transmission chain tension in real time. The main controller precisely controls the current of the electromagnetic coil in the magnetorheological fluid chamber based on the feedback signal. When the transmission chain tension decreases, the magnetic field is strengthened, causing the magnetorheological fluid viscosity to increase, assisting the tensioning component in applying stable tension. When the tension is too high, the magnetic field is reduced to weaken the viscosity, and in conjunction with other structures, pressure is quickly released, achieving precise dynamic control of the chain tension. Furthermore, the magnetorheological fluid responds rapidly to changes in the magnetic field, completing viscosity conversion in a very short time, better ensuring the stable operation of the transmission system. The characteristic of the magnetorheological fluid viscosity changing with the magnetic field provides additional stable support for the tensioning component. After the tensioning component completes tension adjustment, the increased magnetorheological fluid viscosity creates a "damping lock" effect, preventing the tensioning component from shifting due to vibration, impact, or other factors, ensuring continuous stability of the chain tension and reducing transmission failures caused by tension fluctuations.

[0023] 4. By setting up an auxiliary transmission guide mechanism, when the transmission chain deviates during transmission, the Hall switch is triggered when it comes close to the contact point. This activates the air intake pipe to increase the air pressure inside the L-shaped rod, causing the guide body to reset. This corrects the transmission chain, adjusts its movement trajectory, ensures that the transmission chain is transmitted along the correct path, maintains a constant transmission ratio, avoids power transmission interruption or accuracy loss due to deviation, stabilizes the position of the transmission chain, and prevents chain jamming, tearing, or overload of transmission components due to excessive deviation. This reduces sudden failures and downtime losses, and further prevents the deflection motion from aggravating unilateral wear of itself and surrounding components, which could lead to transmission chain stretching, sprocket tooth surface damage, or even breakage.

[0052] The working principle of all the content in the above embodiments is as follows:

[0053] The following describes the working process of the tension adjustment and stabilizing mechanism 2, which is used to adjust the power transmission tension during the overall operation of the loading machine 11 and further assists in adjusting stability during tension adjustment:

[0054] Specifically, the operation process of the first component is as follows:

[0055] During operation, the texturing machine 11 starts. In the process of processing ordinary chemical fiber raw filaments into elastic filaments, the transmission chain 24 is connected to multiple transmission gears 23, thus providing power for the operation of the texturing machine 11. During this process, the transmission chain 24, due to wear, thermal expansion, and other physical changes during prolonged operation, will increase in length, leading to a decrease in tension. At this time, the pressure of the transmission chain 24 on the surface of the tension regulating body 215 changes. With the strain gauges installed on the surface of the tension regulating body 215, this pressure change signal is transmitted to the main controller. The main controller then activates the built-in power supply of the ratchet 28, driving the ratchet 28. During the reverse rotation of ratchet 28, the electrically controlled telescopic rod 210 is in an extended state. At this time, the pawl 211 engages with ratchet 28. With the setting of the outer arc surface of ratchet 28, the pawl 211 and ratchet 28 are in contact and slide along the arc surface of ratchet 28. During the reverse rotation of ratchet 28, the pawl 211 and ratchet 28 abut and engage. At this time, ratchet 28 only rotates in one direction under the restriction of pawl 211, avoiding the transmission of the transmission chain 24 pressing the tension adjustment body 215 and causing the driven toothed disc 213 and ratchet 28 to reverse under the cooperation of multiple structures, thus making the tension adjustment unstable.

[0056] By setting the first component in the tension adjustment and stabilizing mechanism 2, under the extension and retraction control of the electrically controlled telescopic rod 210, the pawl 211 restricts the ratchet 28, preventing the tension adjustment body 215 from reversing when adjusting the tension of the transmission chain 24. Under the restriction of the ratchet 211 on the ratchet 28, the one-way locking characteristic avoids the problem of tension loss of control caused by load fluctuations or unexpected external forces. The meshing characteristics of the ratchet 28 and the pawl 211 determine that the tension adjustment and stabilizing mechanism 2 can adjust the tension in one direction. For example, when the tension decreases, the tension is increased to make the transmission chain 24 tighten. With the assistance of the electrically controlled telescopic rod 210, when the tension is too large, the electrically controlled telescopic rod 210 can be contracted to release the restriction on the ratchet 28, causing it to reverse and reduce the tension. After that, the electrically controlled telescopic rod 210 extends, restoring the one-way locking of the pawl 211 on the ratchet 28, thus making the tension adjustment more flexible while adjusting in one direction.

[0057] Specifically, the second component's operation process is as follows:

[0058] In use, the rotation of the ratchet 28 drives the drive gear 212, which is fixedly connected to it, to rotate synchronously in the opposite direction. Under this movement, since the drive gear 212 meshes with the driven gear 213, the reverse rotation of the drive gear 212 causes the driven gear 213 to rotate in the forward direction. In turn, the forward rotation of the driven gear 213 causes the arc-shaped groove 214 on it to deflect synchronously. This causes the sliding column 216, which is slidably connected in the arc-shaped groove 214, to shift towards the outer ring of the driven gear 213. Furthermore, since the tension adjusting body 215 is slidably connected in the T-slot 27, the tension adjustment body 215 is slidably connected in the T-slot 27. Under the control and the push of the arc groove 214, the tension adjusting body 215 is moved linearly to the outer ring of the positioning disk 26, gradually moving away from the center position of the positioning disk 26. At this time, the diameter of the tension adjusting body 215 relative to the positioning disk 26 expands, thereby increasing the resistance force on the transmission chain 24 sliding on the tension adjusting body 215. With the cooperation of the strain gauge on the tension adjusting body 215, when the pressure of the transmission chain 24 on the tension adjusting body 215 increases to the set value, the tension adjustment of the transmission chain 24 on the surface is completed. At this time, the ratchet 28 stops rotating, thereby controlling the tension adjusting body 215 to stop the outward expansion movement.

[0059] By setting the second component within the tension adjustment and stabilization mechanism 2, and with the cooperation of the tension adjustment body 215 and the strain gauges thereon, the tension of the transmission chain 24 is fed back, thereby adjusting the tension force in a timely manner to ensure that it is always in a reasonable pre-tension state. This avoids transmission misalignment caused by slackness, and thus ensures the stable operation of key components in the texturing machine body 11 that are synchronously transmitted with the transmission chain 24. It also prevents the transmission chain 24 from being too loose or too tight, which could lead to inconsistent rotation speeds of the rollers, causing fluctuations in the yarn draw ratio, sudden changes in yarn tension, and defects such as "stiff yarn" and "loose loop yarn," affecting the fineness uniformity of the finished yarn. By maintaining the stability of the chain transmission, the constant yarn tension is indirectly ensured, thereby improving the product qualification rate.

[0060] Specifically, the operation process of the third component is as follows:

[0061] During use, as the tension regulating body 215 moves towards the outer ring of the positioning disk 26 to adjust the tension, the sliding column 216 moves within the arc-shaped groove 214. Simultaneously, the movement of the tension regulating body 215 drives the guide slider 217 to move linearly within the guide groove 220. The magnetorheological fluid in the magnetorheological fluid chamber 219 is at its initial viscosity. When the tension on the tension regulating body 215 decreases due to the strain gauge feedback transmission chain 24, the strain gauge transmits this signal to the main controller. After the tension adjustment is completed, the main controller increases the current in the electromagnetic coil 221 to enhance the magnetic field strength, causing the magnetorheological fluid in the magnetorheological fluid chamber 219 to... The increased viscosity of the magnetorheological fluid helps stabilize the tension adjustment of the transmission chain 24 by the tension regulator 215, preventing the tension regulator 215 from deviating and compensating for the tension of the transmission chain 24. Conversely, when the tension of the transmission chain 24 is too high, the control system reduces the current of the electromagnetic coil 221, lowers the viscosity of the magnetorheological fluid, and cooperates with the electrically controlled telescopic rod 210. The electrically controlled telescopic rod 210 retracts and contacts the ratchet 28, causing the ratchet 28 to rotate in the forward direction, which causes the tension regulator 215 to move into the positioning plate 26, reducing the pressure of the transmission chain 24 on the tension regulator 215, and thus restoring the tension of the transmission chain 24 to the set range.

[0062] By incorporating a third component within the tension adjustment and stabilization mechanism 2, the tension is adjusted in conjunction with the magnetorheological fluid in the magnetorheological fluid chamber 219. Strain gauges on the tension regulator 215 monitor the tension of the transmission chain 24 in real time. The main controller precisely controls the current in the electromagnetic coil 221 within the magnetorheological fluid chamber 219 based on the feedback signal. When the tension of the transmission chain 24 decreases, the magnetic field is enhanced, causing the viscosity of the magnetorheological fluid to rise, assisting the tensioning component in applying tension stably. When the tension is too high, the magnetic field is reduced to weaken the viscosity, allowing for rapid pressure release in conjunction with other structures. This achieves precise dynamic control of the chain tension. Furthermore, the magnetorheological fluid responds rapidly to changes in the magnetic field, completing viscosity conversion in a very short time, better ensuring the stable operation of the transmission system. The characteristic of the magnetorheological fluid's viscosity changing with the magnetic field provides additional stable support for the tensioning component. After the tensioning component completes tension adjustment, the increased viscosity of the magnetorheological fluid creates a "damping lock" effect, preventing the tensioning component from shifting due to vibration, impact, or other factors, ensuring continuous stability of the chain tension and reducing transmission failures caused by tension fluctuations.

[0064] The following describes the working process of the auxiliary transmission guide mechanism 3, which is used to guide and assist the structure within the tension adjustment and stabilization mechanism 2 to prevent deviation:

[0065] In use, two guide bodies 35 are respectively set on both sides of the transmission chain 24 to provide guidance. During the operation of the texturing machine body 11, vibration is generated, which causes the transmission chain 24 to deviate. The transmission chain 24 exerts a pushing force on the guide bodies 35, which in turn causes the guide bodies 35 to slide into the L-shaped rod 32. The contacts 37 set on the guide bodies 35 move towards the Hall switch 34 in the L-shaped rod 32 at the same time, until the contacts 37 are in contact with the Hall switch 34, triggering the Hall switch 34. As the guide bodies 35 move into the L-shaped rod 32, the L-shaped through hole 3... The through hole 6 gradually slides into the L-shaped rod 32, and then blocks the channel on the side wall of the L-shaped through hole 36 through the inner wall surface of the L-shaped rod 32. At this time, the contact 37 and the Hall switch 34 are triggered to start the external air pump connected to the air inlet pipe 33. Under the action of the air inlet pipe 33, air is supplied into the L-shaped rod 32. The air pressure in the inner cavity of the L-shaped rod 32 increases, and gradually pushes the guide body 35 to move in the direction of the transmission chain 24. Then, under the thrust of the guide body 35 on the transmission chain 24, the transmission chain 24 is assisted to reset, so as to avoid the transmission guide of the transmission chain 24 from deviating, thereby performing the correction operation.

[0066] By setting up the auxiliary transmission guide mechanism 3, when the transmission chain 24 deviates during transmission, the Hall switch 34 is brought close to the contact 37 and triggered, thereby activating the air intake pipe 33 to increase the air pressure inside the L-shaped rod 32 and causing the guide body 35 to reset. This corrects the deviation of the transmission chain 24, adjusts its movement trajectory, ensures that the transmission chain 24 is transmitted along the correct path, maintains a constant transmission ratio, avoids power transmission interruption or accuracy loss due to deviation, stabilizes the position of the transmission chain 24, and avoids chain jamming, tearing, or overload of transmission components due to excessive deviation, reducing sudden failures and downtime losses. Furthermore, it prevents the deflection movement from aggravating unilateral wear of itself and surrounding components, which could lead to stretching of the transmission chain 24, damage to the sprocket teeth, or even breakage.
